Barracuda Features

New, Seagate 1TB-per-disk technology marks another major milestone for the hard drive industry. To make this happen, Seagate engineers had to pack 340,000 hard drive tracks into the width of a single inch. This means that, when reading and writing data, the read/write head needs to accurately follow a track that is a mere 75 nanometers wide. That's about 500 times smaller than the period at the end of this sentence.

Seagate AcuTrac technology helps enable this incredible feat-reliably and accurately following these nano-tracks even in challenging operating environments, like an all-in-one PC with the music turned up.

Seagate OptiCache Technology Continues to Push Performance. Barracuda 1TB-per-disk hard drives now include a host of refined technologies to further boost performance. Combined, these improvements squeeze even more performance out of storage already known for pushing the envelope!

Key Advantages

  • Third-generation dual-core processor with integrated ARM handles more data faster.
  • 40nm chip manufacturing technology delivers more computing power without increasing electrical power requirements.
  • 64MB of DDR2 SDRAM enables the fastest cache yet on Barracuda drives.
  • Double your capacity and drive down costs with the industry's first 1TB-per-disk hard drive technology.
  • Up to 3TB capacity with 7200-RPM performance. Why compromise?
  • SATA 6Gb/s interface optimizes burst performance
  • Seagate AcuTrac servo technology delivers dependable performance, even with hard drive track widths of only 75 nanometers.
  • Seagate OptiCache technology boosts overall performance by as much as 45% over the previous generation.
  • Seagate SmartAlign technology provides a simple, transparent migration to Advanced Format 4K sectors.
  • Free Seagate DiscWizard software allows you to install a 3TB hard drive in Windows, including XP, without UEFI BIOS.

Best-Fit Applications

  • Desktop or all-in-one PCs
  • Home servers
  • PC-based gaming systems
  • Desktop RAID
  • Direct-attached external storage devices (DAS)
  • Network-attached storage devices (NAS)

I just finished retesting my two Western Digital Caviar 640 Blacks and used a lot of the same tools you did. (My reasons weren't to compare this drive but other tests I was doing unrelated.)

One of the things I wanted to do was test using real files. I chose to use a folder with 6GB of jpg/RAW/and video files. I then compressed that entire folder into a solid RAR archive and tested with that as well. Synthetic benches are fun, but real world file transfers can tell a different story.

All in all a tight review, but I'm wondering why you didn't test the drive using real files, say reading from an SSD and writing to it?

I could have used real files, but felt I already had enough tests completed to illustrate performance. When you use real files, they must be the exact same files every time. Compressed files (mov/avi/mpg/etc) also skew results depending on the SSDs used.

When you say "skew" results, you mean because SSDs take into consideration compressible files as opposed to uncompromisable files? If so, that's why I created a compressed RAR file and the folder with loose files in it. It would have just been nice to see two real world file transfer scenarios, as per above. Maybe I'm off base here. If so, disregard.

I've done some comparisons like this during my NAS tests: "Instead of one 10 GB file, the green portion of the chart shows what happens when transferring 4,793 items totaling 6.5GB from the PC to the NAS. If you're going to use any NAS for basic backup duties, this is the kind of action it's going to see." My informal tests showed that the real-world examples introduced too much variation in the results, making comparisons difficult and/or misleading.

Still, I get your point, and I also wish there was a way to use a standardized set of test files, that everyone could agree on.

Since here only two drives were being compared to each other, the same files could have been used for both drives. One, as explained above, multiple file, and the other one large file. Because as you point out, drives act differently depending on what is being transferred.

I suppose you could save those same files and use them to test other drives also, albeit, with the same drive and rig set up. Or, one could test a number of drives using the same files on any rig, as long as the host drive, to prevent bottlenecking, is faster than the drive being tested. That SSD Olin tested recently would have been a good contender for the host drive, since it is the fastest SSD currently commercially available to the public.

does this drive work with sata 2 raid controllers?

Yes, SATA 6Gb/s is backwards compatible with SATA 3Gb/s and 1.5Gb/s.

I have both the Workstation and the Sabertooth motherboards with the P55 chipset and if they are the same as the X79 the Sabertooth compared to the Workstation are the same my p55's. The Sabertooth was able to OC 300 mhz more then the workstation 4.3Ghz for the Workstation comaper to the Sabertooth able to clock to 4.6Ghz.
